Abstract

The invention discloses a rain-proof and sound-absorbing hood, which is composed of a top umbrella cap, a sound-absorbing and diversion cone, a circular tube-shaped rain-proof and sound-absorbing board, an installation load-bearing structure, and a diversion and sound-absorbing insert. The top umbrella cap is arranged above the chimney air outlet; the cone bottom of the sound-absorbing guide cone is arranged in the top umbrella cap, and the cone tip is facing the airflow direction of the chimney air outlet; the circular tube-shaped The rainproof and sound-absorbing panels are arranged vertically, the upper part is connected with the top umbrella cap edge, and the lower part is lower than the air outlet of the chimney. The installation load-bearing structure is composed of a supporting vertical groove, a supporting horizontal groove, an upper flange, and a lower flange. The supporting vertical groove is vertically connected to the top umbrella cap and the upper flange, and the supporting horizontal groove is horizontally connected to a round pipe-shaped rainproof and sound-absorbing The plate, the support vertical groove, the lower flange are welded on the chimney wall, and the upper flange and lower flange are connected by bolts. It can not only meet the ventilation requirements but also prevent rainwater invasion, and has a high effective ventilation rate, simple manufacture and installation, and high noise reduction.

Description

technical field [0001] The invention relates to a chimney wind cap, in particular to a rain-proof and sound-absorbing wind cap which is installed at the air outlet of the chimney and has the functions of noise reduction and rain protection. Background technique [0002] Chimney rainproof cover The rainproof cap is something similar to an umbrella. It consists of a conical or hemispherical umbrella cap and several support rods. It is generally used on vertically upward vent pipes and chimneys to prevent rainwater from entering the pipe. [0003] In order to discharge exhaust gas normally, the exhaust gas of the chimney is often discharged through the pressurized fan, which inevitably radiates the noise of the fan and equipment through the air outlet of the chimney. Since the chimney is set at a high position and there is no effective barrier to block it, resulting in a considerable area around The environment is affected by noise, which has a great impact on noise sensitive p...
